GEORGE W. BLAKE, OF NEW YORK, N. Y.

HANGER Foe PIPE.

SPECIFICATION forming part of Letters Patent No. 311,282, dated January27, 1885.

Application filed September 1l, 18 84. (No model.)

550 all whom, it may concern:

Be it known that I, GEORGE W. BLAKE, of the city and county of New York,in the State of New York, have invented a new and use ful Improvement inI-Iangers for Pipe, of which the following is a specification.

My invention relates to hangers whereby steam, gas, or water pipes aresuspended or hung from fioorbeams or other supports, and an importantobject of my invent-ionisto provide a hanger which may be readilyapplied to pipe already connected or placed without disconnecting thepipe, in case the hangers have been overlooked or employed ininsufficient number, or in case it is desired to apply them to an oldline of pipe.

The invention consists, essentially, in the combination, with an eyeboltor equivalent support, of a yoke or stirrup adapted to embrace the pipe,pivoted to the said bolt or support, and composed of two sections whichare separately connected or interlocked at their lower portions in suchmanner that they cannot become detached from each other so long as theirupper ends remain pivoted to the eyebolt or support. Vhen desired toremove the hanger from the pipe, the pivot bolt or pin is removed orslipped back, and the two sections of the yoke or stirrup can then beunlocked or disconnected and removed laterally from the pipe. The hangermay be applied to the pipe by an operation or in a manner the reverse ofthe above.

In the accompanying drawings, Figure 1 represents a hanger embodying myinvention. the yoke or stirrup being shown slightly in perspective. Fig.2 is asectional view of the hanger. Fig. 3 represents a piece of pipe indotted outline and a pair of hangers supporting the same; and Figs. 4cand 5 are respectively vertical and horizontal sectional views of a yokeor stirrup of modified form, but also embodying my invention.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the support for the yoke or stirrup B B. As here shown, thesupport consists of a lag-screw or screw-bolt having an eye, a, at thehead, and capable of being fastfined in floor-beams O or other suitablesupports. The yoke or stirrup is of cast or other metal, made in twosections, 13 B, which are interlocked or detachably connected at theirlower portions, and at their upper ends are pivoted, by a bolt, 1), orpin, to the eyebolt A.

The yoke or stirrup B B will be made of any size necessary to embrace orsurround the pipe to which it is to be applied, and the eyebolt orsupport A will be of any length adapted to the circumstances.

The two sections of the yoke or stirrup may be interlocked orconstructed to interlock in any suitable manner. As shown in Figs. 1 and2, the two sections are rabbeted or halved together-that is, they areprovided with shoulders and overlap one another. The part or section Bhas a projecting spur or stud, 0, and the part B an eye or hole, (1, toreceive the same. \Vhen thus secured or connected. together, thesections can be unlocked or disconnected only by an upward movement ofthe section B sufiicient to lift its eye or hole.

(Z off the pin or stud c, and such movement cannot be made so long asthe pivot bolt or pin 1) is in place. Consequently the two sectionsremain-connected and cannot be unlocked or parted until the nut of thebolt or pin b is removed and the bolt or pin is shoved back sufficientlyto enable the section B to be moved outward away from it, whereupon thesection B may be lifted off the pin or stud c, and thus separated fromthe section B.

In the example of my invention shown in Figs. i and 5 the section B hasa notch or socket, (1*, and the section B a head or tongue, 0*, adaptedto be engaged therewith, the notch or socket and tongue or head beingcorrespondingly dovetailed to prevent their lateral separation, andextending the full depth of the thickness of metal at the connected endsof the sections. To separate these two sections also, it is necessary tofirst remove the nut of the bolt or pin 1) and shove the latter backuntil the sect-ion B can be drawn or moved backward off the bolt or pin,and then raised to free its tongue or head 0* from the notch 01*.

The hangers may be employed to sustain a pipe, D, as shown by dottedlines in Fig. 3, and as the yokes or stirrups are pivoted to theireyebolts or supports, they can move or swing slightly in the directionof the line of pipe as the latter elongates or contracts by differencesin its temperature.

WVhat I claim as my invention, and desire 5 to secure by Letters Patent,is

1. In a pipe-hanger, the combination, with an eyebolt or other support,of a yoke or stirrup composed of two sections pivoted to said bolt orsupport and detachably connected or 10 interlocked at their lowerportions, substantially as and for the purpose herein described. 7 2.The combination, with the eyebolt orsupport, of the yoke or stirrupcomposed of the two sections B B, halved together as described, andconstructed one with a stud or projection and the other with an eye orsocket to receive the same, whereby they are detachably connected orinterlocked, substantially as and for the purpose herein described.
